Feasibility of Fine Classification in Processing Watered Coal Sludge from Storage: A Case Study of the Dnipro Coke Chemical Plant

significant branches of Ukraine’s economy, contributing
substantially to national GDP and employment. However, these
sectors are also major sources of environmental pollution,
particularly through the generation of substantial volumes of liquid
industrial waste. A notable portion of this waste includes finedispersed coal sludge from coke-chemical production, which poses
serious risks to ecosystems and public health if not properly
managed. This research addresses the urgent need for effective
processing of such waste, demonstrating the feasibility and economic
viability of obtaining marketable secondary products through
advanced fine classification methods in the 0.05–0.1 mm fraction
range, combined with simultaneous dewatering techniques. By
implementing these technologies, it is possible to significantly reduce
the accumulation of hazardous waste in storage facilities, thereby
minimizing environmental damage and the associated long-term
remediation costs. This approach contributes to the circular economy
by recovering valuable resources from waste streams, thus enhancing
the overall profitability and sustainability of industrial operations.
The study underscores the importance of integrating low-waste
technologies, efficient raw material utilization, and cross-sectoral
cooperation to develop a modern system of waste management. Such
integration ensures not only the minimization of environmental harm
but also supports Ukraine’s transition towards more sustainable
industrial practices and compliance with European environmental
standards. The proposed solutions offer a practical pathway to
achieving both ecological and economic resilience in the context of
post-war recovery and industrial modernization.
